Overview of this book

Starting with an introduction to the newly released features of PostgreSQL 15, this updated fifth edition will help you get to grips with PostgreSQL administration and how to build dynamic database solutions for enterprise apps, including designing both physical and technical aspects of the system. You'll explore advanced PostgreSQL features, such as logical replication, database clusters, advanced indexing, and user management to manage and maintain your database. You'll then work with the PostgreSQL optimizer, configure PostgreSQL for high speed, and move from Oracle to PostgreSQL. Among the other skills that the book will help you build, you’ll cover transactions, handling recursions, working with JSON and JSONB data, and setting up a Patroni cluster. It will show you how to improve performance with query optimization. You'll also focus on managing network security and work with backups and replication while exploring useful PostgreSQL extensions that optimize the performance of large databases. By the end of this PostgreSQL book, you’ll be able to use your database to its utmost capacity by implementing advanced administrative tasks with ease.

Understanding developer-related features

Administration-related features are not everything. PostgreSQL 15 also provides some developer-related features that are useful to build even more powerful applications. In this section, you will learn which ones are available.

Security invoker views

In PostgreSQL, a view is a separate security context. It might happen that somebody is allowed to access a view but not the underlying table. Why does this matter? Consider the following scenario:

  • Joe is allowed to see all sales
  • Jane is only allowed to see total turnover by country

Jane will be granted rights on a view that sums up the data. She will be able to read that view without having the right to read the sales table directly.

However, in PostgreSQL, it is now possible to make PostgreSQL treat the view more like a preprocessor directive. By setting security_invoker, it will also check the underlying tables and not treat the view as a separate security context anymore...
